Aerospace Companies In Maryland Are Developing Futuristic Spacecraft

By Pamela Gray


On a murky day a long time ago, a creature stood up and gazed at the sky to wonder at the vastness of the space. Often wandering in search of food and shelter, its mind veers off this activity to look up at the heavens. Not much has changed today even with the web of activities that man does and aerospace companies in Maryland provides an opportunity for enthusiasts to explore space.

The universe is a vast ocean of nebulae, suns, stars, planet and other space objects. Scientists say it is still expanding as observations have been made of heavenly bodies travelling further and further from the earth. Large clouds of dust occupy much of the universe. These are electronically charged particles that are in constant collision.

Other forces were also in play during this event, from where it came from nobody really knows. What is known is that huge masses that were created exerted gravity that pulled other objects to it. The galaxy is a child of this explosion and is home to millions of stars, suns, and planets. This system is spiral in form and is murky hence the name Milky Way.

Within galaxies are systems that are mostly dominated by huge stars that exert a pull on other objects. The forces make it orbit around the sun in fixed paths. The system is scientifically termed as a solar system. This system basically is a huge star with several planets revolving around it. Other objects not of the system travel through it in cycles.

Earth is but a tiny speck in the scheme of things. It is like a grain of sand when placed in context of Universal vastness. But it does harbor life both plant and animals and many more. The ground is where most of these are found and beasts habituate in the great forests and woodlands. The oceans surround the dry land is home to the fishes.

Flying like a bird has always been an ambition of man. It came to fruition with the invention of airplanes. The early models had wings shape like that of bird. Many an adventurer has been killed in flimsy flying machines. A huge step in the history of flight was the development of a lightweight engine that could be mounted on a frame and have enough power to achieve flight.

This contraption has evolved tremendously over the years. Races were organized that stimulated rapid development. Early models were made of fabric and wood. Today almost all are constructed of metal in its various states. Developments in engine technology also hastened the modernization of aircraft. Originally these were propeller driven and powered by engines mounted in the framework.

The jet engine was simultaneously developed by two nations. These did have no propeller attached to it, instead, it uses air that is sucked the engine and blown out at the other end. It was more powerful and more fuel efficient that it can make an airplane travel at more than five times the acceleration of sound. Military and commercial aircraft have engines of this type.

People say that the last frontier is space. Nations have space programs with the purpose of exploring space beyond earth. Rich and powerful nations have place men into orbit around the earth using rocketry to thrust the vehicles free from planetary gravity and atmosphere. Satellites are launched into space using rockets, so far it is the only way to hurl huge object into the sky.
